Title: Unlocking the potential of Philippine rice germplasm for varietal
development to mitigate impact of climate change
気候変動への対応を目指したイネの品種改良 〜フィリピンにおける遺伝資源の潜在能力を解き放つ〜

Presenter: Jonathan M. Niones PhD. (Chief Science Research Specialist and Head of Genetic Resources
Division, Philippine Rice Research Institute, Science City of Muñoz, Nueva Ecija, Philippines)

The Philippine rice industry sector is constantly challenged by yield -limiting factors affecting the nation’s rice productivity andfood security. The rice varietal program of the Philippine Rice Research Institute (PhilRice) aims to address these challenges thru
development and promotion of high yielding, good eating quality and biotic and abiotic stress- resistant varieties. A diverse ricegenetic resources is one of the key components of a successful and sustainable varietal development program. Vast collection ofrice germplasm is a good source of alleles of important traits that serve as the foundation of any rice breeding program.
The PhilRice Genebank, the country’s national repository for rice germplasm, currently conserves 16,724 rice accessions and thenumber is increasing as collection is being intensified across the country. These include landraces, wild rice, weedy rice,
traditional rice varieties and elite lines. Aside from conservation efforts, these germplasms are being characterized and profiled
for their potential as genetic donors for various traits such as high yield, good grain and eating quality, insect pest and disease
resistance, and tolerance to various abiotic stresses. Identified promising rice germplasm with novel genes are being utilized in
the varietal improvement program.
PhilRice Genebank uses the Germplasm Management System (GEMS), a relational database management system to document,manage, and centralize the large quantities of data. The rice germplasm accessions' passport data, characterization andevaluation data are validated and uploaded in the GEMS database system. GEMS maintains accurate, reliable and up-to-date rice
germplasm information for better access search and retrieval of germplasm. Information found in the GEMs are germplasm dataon passport, morpho-agronomic characterization, grain quality, pest (BPH, GLH, SB) and diseases (RTV, blast, BLB, sheath blight)
and abiotic stresses evaluations; viability conditions, and seed inventories.
In this presentatio, rice germplasm conservation program at PhilRice Gene bank and how these genetic resources arecharacterized and explored, will be highlighted. Moreover, the presentation also provides information on the contribution ofgenetic materials in the rice varietal improvement and the future direction of rice germplasm conservation.
フィリピン稲研究所では、多収、高品質、生物・非生物的ストレス耐性などを有するイネ品種の育成を目指しており、これには多様性に富んだ遺伝資源の保全・利用が必要不可欠である。現在、同研究所ジーンバンクには16,724におよぶイネのアクセッションラインが保存されており、現在もなお新たな資源を国中から収集し続けている。これらを遺伝資源管理システムにより一括管理することで、多様な遺伝資源の効率的な利用が可能となる。
今回は、フィリピン稲研究所ジーンバンクにてどのようにこれらの遺伝資源特性がデータ化され、またどのように品種改良に利用されているのかについて、今後の遺伝資源保全の方向性についても交えつつ紹介したい。
